Comfortable calibration routine with selective access release is integrated in the transmitter. The CO detector, and -series possesses a standard analog output (0)2-10 Vdc or (0)4-20 ma. As option RS-485 interface and 2 relays with adjustable switching thresholds are available. Due to the standard analog signal the CO detector is compatible to DDC and PLC.

Advise the thresholds for Low-and-High alarm when ordering relay pack RP2. LCD Display (LCD) in comination with Relay pack (RP2) and Buzzer (BZI) not available. LCD Display (LCD) in comination with Relay pack (RP2) available. LCD Display (LCD) in comination with Buzzer (BZI) available. Important notes before ordering: The recommended storage life is up to 6 months unpowered, Carbon Monoxide (CO) detectors are manufactured on request. As the storage life for Carbon Monoxide (CO) detectors is up to 6 months unpowered we want pre-payment before process the order to production department, this to avoid any cancellation of order. Delivery time is normally 4 weeks after receipt
